【问题描述】：

我有两个字典如下

"fictional_characters": {
   "male": [
      "Donkey",
      "Humpty",
      "Piranha"
   ],
   "female": [
      "Fiona",
      "Kitty_Softpaws",
      "Diane_Foxington"
   ]
}

和

"movie_names": {
   "Donkey": "Shrek",
   "Humpty": "Puss_in_Boots",
   "Piranha": "The_Bad_Guys",
   "Fiona": "Shrek",
   "Kitty_Softpaws": "Puss_in_Boots",
   "Diane_Foxingtin": "The_Bad_Guys"
}

我想将“fictional_characters”中的字典值更改为“movie_names”中的值，例如

"fictional_characters": {
   "male": [
      "Shrek",
      "Puss_in_Boots",
      "The_Bad_Guys"
   ],
   "female": [
      "Shrek",
      "Puss_in_Boots",
      "The_Bad_Guys"
   ]
}

我首先将“fictional_characters”字典转换为列表

- name: Convert fictional_characters to a list
  set_fact:
    fictional_characters_list: "{{fictional_characters | dict2items }}"

那给了我

"fictional_characters_list": [
  {
    "key": "male",
    "value": [
      "Donkey",
      "Humpty",
      "Piranha"
    ],
  },
    "key": "female",
    "value": [
      "Fiona",
      "Kitty_Softpaws",
      "Diane_Foxington"
    ]
  }
]

接下来，一些金贾

- name: Using Jinja to swap dict values
  set_fact:
    fict_char_movies: |
      {% for e in fictional_characters_list %}
      {{ e.key }}:
      {% for char in e.value %}
      {% if char in movie_names %}
        - {{ movie_names[char]|split(',') %}
      {% endif %}
      {% endfor %}
      {% endfor %}

- name: Print the result
  debug:
    msg: "{{ fict_char_movies | from_yaml }}"

以上返回以下结果

"male": [
  [
    "Shrek"
  ],
  [
    "Puss_in_Boots"
  ],
  [
    "The_Bad_Guys"
  ],
"female": [
  [
    "Shrek"
  ],
  [
    "Puss_in_Boots"
  ],
  [
    "The_Bad_Guys"
  ]
]

如何摆脱这个嵌套列表，以便获得以下结构？

"fictional_characters": {
   "male": [
      "Shrek",
      "Puss_in_Boots",
      "The_Bad_Guys"
   ],
   "female": [
      "Shrek",
      "Puss_in_Boots",
      "The_Bad_Guys"
   ]
}

【解决方案1】：

下面的声明

  fict_char_movies_str: |
    {% for k,v in fictional_characters.items() %}
    {{ k }}:
    {% for char in v %}
    {% if char in movie_names %}
      - {{ movie_names[char] }}
    {% endif %}
    {% endfor %}
    {% endfor %}
  fict_char_movies: "{{ fict_char_movies_str|from_yaml }}"

给你想要的

  fict_char_movies:
    female:
    - Shrek
    - Puss_in_Boots
    - The_Bad_Guys
    male:
    - Shrek
    - Puss_in_Boots
    - The_Bad_Guys

- hosts: localhost

vars:

fictional_characters:
female:
- Fiona
- Kitty_Softpaws
- Diane_Foxington
male:
- Donkey
- Humpty
- Piranha

movie_names:
Diane_Foxington: The_Bad_Guys
Donkey: Shrek
Fiona: Shrek
Humpty: Puss_in_Boots
Kitty_Softpaws: Puss_in_Boots
Piranha: The_Bad_Guys

fict_char_movies_str: |
{% for k,v in fictional_characters.items() %}

{% for char in v %}
{% if char in movie_names %}
- {{ movie_names[char] }}
{% endif %}
{% endfor %}
{% endfor %}
fict_char_movies: "{{ fict_char_movies_str|from_yaml }}"

tasks:
